223 lapua brass necked down to 222

[ArtinNC]

I got a new 222 match chamber reamer and come with the neck was .036 longer than the std 222 . so I had some 223 lapia match brass that I necked down to 222 to have a longer neck ,the necks are now .030 longer . Becase It would have made a longer carbon ring in my chamber that I didn't want . I formed it with a Redding trim die , run the brass thru a Redding bushing die , then a expander die , turned the necks to .012 , annealed the brass , and debured case mouth . Today I loaded the rounds and I noticed that some of the bullets seated harder than some of the others ( using Berger 52 match bullets ) , I would think they would feel about the some when setting the bullets beings I mic everyone . This is for fire forming only so not to worried about that till my next loading .

Could some of the brass be a little thicker in the neck, even though you trim to .012 and thus casing a little harder seating of the bullet ? Just a thought. might need some reaming. Or does that make sense ?

((Just a thought. might need some reaming.)) I may ream after fire forming ,just have to see .

after anealing did you brush inside the necks? and did you use any lube?

No ! guess that is why , guess that answers that . . I do brush necks after fired .

Are the bullets just harder to start or harder to press all the way?

You didn’t mention a chamfer on the inside of the neck, even reaming wouldn’t really do that. small flat base bullets need all the help they can get.

 

[ArtinNC]

Harder to press in . I debured ( chamfer ) the case for the flat base bullets . After I fire from them I will anneal again and see if that helps .
Trying to get everything the same ,trying to get 5 shots in the same hole like I can my 6 br .
